It came out in 1989. Sadly around the same time as the Honda RC30, which did much better on the race track, and hence the poor Yam has been largely forgotten with time ....
Yet, in 'stock' form it was a LOT closer to the bikes racing than the RC30 was, and it was also a LOT more expensive than the RC.
It's hard to believe this bike is now 18 years old !! ... or am I just developing 'old man' syndrome ....
Aluminium perimiter frame, titanium valves, remote preload, 17" wheels, twin headlights, pressurised airbox, exup valve, 45 degree sloping heads, downdraft carbs (nearly every other bike at the time had side draft carbs .. and steel perimeter frames !!).
And .. take a look at the brake calipers and discs. They could be off any contemporary sports bike.
